Decoding for calcium imaging #285

Open ZhaomingPsych opened 5 months ago

ZhaomingPsych commented 5 months ago

Hi everyone, I have some questions regarding the shuffle method, tuning curves, and decoding in your library:

  1. Shuffle Method: Is the TsDataFrame suitable for the shuffle method? Can TsDataFrame be transformed into a TsGroup?
  2. Tuning Curves: It appears that Tsd cannot be used as an input for tuning curves, despite the documentation indicating that it should be possible.
  3. Decoding: Can TsDataFrame be used as an input for the decoding process?

Thank you for your assistance.

Hey,

  1. Currently the shuffle methods works only for timestamps object (Ts) or TsGroup. In what case would you want to shuffle a TsdFrame? In any case, you can transform a Tsd into a TsGroup but not a TsdFrame.
  2. Which function did you try to use?
  3. Not yet. It's in the roadmap. Feel free to describe your use case here.

Thank you for your reply!

  1. You're right! I transformed TsDataframe to Tsd, and now it works!
  2. compute_1d_tuning_curves_continuous
  3. Currently, I am trying to analyze place fields from two-photon calcium imaging using pynapple. Our goal is to decode the mouse's position from the calcium imaging data. Do you have any suggestions?

For 3. it's in the roadmap to add more capabilities for decoding with calcium imaging data but it's not ready yet. I would just try to train a machine learning model from scikit-learn if you want to do some decoding. I can leave this issue open until new decoding functions are implemented.
